Nest-mate recognition plays a key role in the biology of ants. Although individuals coming
from a foreign nest are, in most cases, promptly rejected, the degree of aggressiveness …

Broadly applicable polymorphic genetic markers are essential tools for population genetics,
and different types of markers have been developed for this purpose. Microsatellites have …

The colony structures of social insects vary greatly among species. In ant societies, the
number of queens within a colony is variable during colony maturation. We investigated the …

Natural habitats with serpentine soils are rich in heavy metal ions, which may significantly
affect ecological communities. Exposure to metal pollutants results, for instance, in a …

In this study we investigated the relationship between spatial distance and intraspecific
aggression in the Mediterranean tree-nesting ant Crematogaster scutellaris. Aggression …

Mieren zijn polyfage predatoren die territoriaal en coöperatief gedrag vertonen,
eigenschappen die hen interessant maken voor de biologische bestrijding van …

Among eusocial Hymenoptera, ants represent an unrivalled example of diversity in number
of queens and mating systems. Ant colonies may have one (monogyny) or several queens …

Interspecific hybridization is a relatively common occurrence within all animal groups. Two
main factors make hybridization act differently in ants than in other species: eusociality and …

Species delimitation is fundamental for many biological studies; its importance extends from
regional faunistics over behavioral research to the reconstruction of evolutionary history …

DISCUSSION The high level of relatedness between workers sampled from different but
spatially close nests supports the hypothesis of a polydomic arrangements of nests of this …
